1.0. INTRODUCTION Most air conditioning and heating systems require some form of duct work to channel or direct the air to places where the conditioned air is needed. There are many types of ductwork available and often times the ductwork can make a big difference in your utility bills. For that reason, it is
The emphasis is on vibration measurement systems from a field perspective considering transducer types and configurations, vibration transmissibility, and typical diagnostic considerations used to quantify vibration severity and fan mechanical condition. INTRODUCTION Regarding the current industrial specifications and codes prescribed for vibration
Refer to the ARI Unitary Directory for ratings with specific condensing units. ** Needed capacity of a conventional system to provide the same comfort of the Unico System will vary depending on humidity load. *** Based on 33 to 40 CFM (15 to 19 L/s) per outlet. Verify minimum total system airflow.
